TL;DR
Polymarket has turned to Chainalysis as it seeks to strengthen oversight of trading behavior while pursuing a $400 million fundraising round and working toward approval to relaunch in the U.S. The company said the partnership is meant to reinforce its stance against insider activity and other forms of manipulation by using blockchain‑verified evidence to support regulatory engagement. The move comes as the platform aims for a $15 billion valuation and attempts to reenter the U.S. market under the eye of the Commodity Futures Trading Commission.
The agreement brings multiple Chainalysis tools into Polymarket’s monitoring framework, including investigative capabilities designed to surface patterns linked to insider knowledge. The solution expands on the platform’s existing systems and is built to evolve as new threats emerge. Chainalysis will also provide professional services, training, and support for complex investigations. Executives from both companies said the collaboration reflects a shared belief that transparent, traceable on‑chain activity can set a new standard for market integrity across prediction markets.
Polymarket’s push for stronger oversight comes as it works to regain ground in the U.S. after settling with the CFTC in 2022 for allegedly offering illicit binary options. The company later launched a U.S. version of its platform after acquiring QCEX, a regulated derivatives exchange. As trading volumes rise across the sector, both Polymarket and rival Kalshi have been under pressure to address concerns about insider behavior while competing for multi‑billion‑dollar valuations and broader market share.

Polymarket leadership emphasized that the platform’s on‑chain structure is central to its approach. Every trade, position, and settlement is recorded publicly, allowing activity to be traced in real time. The company said pairing that transparency with Chainalysis’ detection models strengthens its ability to identify misconduct and maintain trust. Chainalysis executives added that the collaboration demonstrates how on‑chain markets can offer a level of visibility that traditional systems cannot match.
Recent academic research analyzing Polymarket transactions from 2023 through 2025 found that 3.14% of accounts qualified as skilled winners whose order flow consistently predicted short‑term moves and final outcomes. This informed minority, along with market makers, captured more than 30% of gains while representing under 3.5% of accounts. The findings suggest that accuracy on the platform often reflects informed participants rather than broad crowd consensus.
